Abstract: This paper analyses characteristics of the recent explosion of patent filings by Chinese firms both domestically and in the United States. We construct a firm-level dataset by matching USPTO and SIPO patents to Chinese manufacturing census data for 1999-2006. Using this integrated dataset we show that the patent explosion is accounted for by a tiny, highly select group of Chinese companies in the ICT equipment industry. Our analysis further suggests that firms patenting in both the US and China are younger, larger and more export-oriented than firms patenting exclusively in China.
